An AI sales agent's dishmachine order, checked before it goes out

An AI sales agent prepares an order for a commercial conveyor dishmachine from a public sell sheet, choosing the machine size, hood, sanitizing mode and electrical supply for a kitchen. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the sell sheet and returns a verdict, every reason and the figures it computed.

Scope: Ecolab EC-LW conveyor dishmachines: 44 or 66 inch, standard or high hood, low-temp or high-temp sanitizing, electrical supply, water supply, temperatures, chlorine, throughput and item height. See everything this validator covers

This validator models orders for the Ecolab EC-LW conveyor dishmachine family (EC44-LW, EC44HH-LW, EC66-LW, EC66HH-LW), not just the scenarios shown below.

  • Electrical supply — the sell sheet gives a minimum circuit size for each size, phase and voltage (three-phase 208, 230 and 460 volts; single-phase 208 and 230 volts only); the site circuit is compared with it, single phase at 460 volts is rejected, and a stated circuit size that disagrees with the sell sheet is rejected.
  • Water and temperatures — minimum incoming water of 120 degrees F (low-temp) or 180 degrees F (high-temp), wash minimums of 140 or 160 degrees F, sanitizing rinse minimums of 120 or 180 degrees F, a flow pressure of 15 to 25 psi, a water line of at least 1/2 inch and a 1 1/2 inch drain line; low-temp water below the recommended 140 degrees F goes to a person to confirm.
  • Chemical, throughput and fit — a minimum of 50 ppm chlorine for low-temp sanitizing, throughput of up to 244 racks an hour, and an item height within the wash chamber (18 inches standard, 25 inches high hood).

Any order for this machine family that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (Ecolab lists none for these machines, so this validator produces no price build-up or line-item quote), the rental program terms, the sideloader option, water consumption (the sell sheets give different figures), dispensers and chemical programs, other Ecolab dishmachines, and local code requirements.

The AI sales agentBuilds the dishmachine order from the conversation and says it is ready.
Predictika validatorChecks every rule at once and returns the verdict, each finding, and the computed figures.

Where rules-based CPQ gets it wrong
Click to expand
    
Our assessment of what a typical rules-based CPQ (product rules, price rules and validation rules, as in Salesforce CPQ) does with the same cases. It is a judgment about effort and reliability, not a claim that nothing can be built.

    
What the validator caughtTypical rules-based CPQPredictika
A minimum circuit that depends on size, phase and voltageOnly with care
The circuit table has a different value for each combination, so it takes a lookup per combination and a comparison with the site circuit.		Size, phase, voltage and the site circuit travel in one request; the minimum is looked up and compared on every call.
Temperature minimums that change with the sanitizing modeOnly with workarounds
Low-temp and high-temp machines have different minimums for incoming water, wash and rinse, so the rules multiply and are easy to miss when a mode is added.		The mode is part of the request and every temperature is compared with the minimum for that mode.
A stated circuit size that disagrees with the sell sheetOnly with workarounds
The figure the agent states is free text or a separate field, so it takes an extra rule that compares it with the table value.		The stated figure is part of the request and is compared with the sell-sheet figure on every call.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the order is saved or a step is completed, so a rep often fixes one error and meets the next.		All findings come back together, whatever order the choices arrived in.

Every rule is checked on every call, in any order the choices arrive; one problem never hides another. Blocking findings stop the quote; approval findings need a person to sign off; everything else is computed.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares an order for a commercial conveyor dishmachine from a public sell sheet, choosing the machine size, hood, sanitizing mode and electrical supply for a kitchen. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the sell sheet and returns a verdict, every reason and the figures it computed.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote an Ecolab EC-LW 66 inch high-hood low-temp conveyor dishmachine on a 208 volt single-phase supply. It is ready to send. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with five findings, all in one answer. The site circuit is 90 amps; the sell sheet gives a minimum circuit of 100 amps for this model, phase and voltage. The incoming water is 110 degrees F; the sell sheet gives a minimum of 120 degrees F for the selected sanitizing mode. Low-temp sanitizing is selected with 40 ppm chlorine; the sell sheet gives a minimum of 50 ppm chlorine for low-temp operation. The other two are on screen.
    6. 
      
  6. The validator returned five blocking findings in one answer. A check that reads one field at a time would pass most of this; it shows only when the choices in the quote are checked against each other.
    7. 
      
  7. What this shows: for a stated circuit size that disagrees with the sell sheet, a rules-based CPQ can do this only with workarounds.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the site circuit to 100 amps, the incoming water to 140 deg F, the chlorine to 50 ppm, the flow pressure to 20 psi, the tallest item to 26 inches and the stated minimum circuit as to 100 amps.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. Still blocked, with one finding, all in one answer. The tallest item is 26 inches; the selected hood gives a wash chamber height of 25 inches (18 inches standard, 25 inches high hood).
    12. 
      
  12. Five findings cleared, but the change brings a different blocking finding: item taller than the wash chamber.
    13. 
      
  13. The agent resubmits once more.
    14. 
      
  14. The revised request. It changes the tallest item to 24 inches.
    15. 
      
  15. It calls the validator once more.
    16. 
      
  16. This time the validator clears it.
    17. 
      
  17. The earlier finding is cleared, and the validator's figure matches the quote.
    18. 
      
  18. Five problems caught in one call, fixed in two passes, and a clean quote. That is the value of Predictika's validator: catching mistakes before they reach the customer.
    19.
